Add support for full bottom fill on iPhone X

[beardo01]

Whenever I create a Flushbar on an iPhone X/XS device there is a gap between the bottom of the screen and the Flushbar. Ideally, the background would colour this part of the screen.

Hi @beardo01
Can you attach a picture, please?

Unless flutter gives me an option to paint the gesture bar, I can't solve this problem. I will do some research to see if that is possible without disrupting the package.
In the meantime, you can use it at FlushbarPosition.TOP or give it some aroundPadding and
borderRadius to try a more simetric feel with the gap.

Right now the bottom appearance has a wrong position on the iPhone X. Look at the attached image.

@cetorres Can you add flutter doctor output here and some code so we can reproduce?

Any new about this. I had the same issue with the bottom gap I'd like a way to fill with the snack color.
